Conclusions
-
1.
Nuclear electric power generating stations based around a VK-50 reactor differ from other power stations based around boiling-water reactors in the typically high content of copper and zinc compounds in the deposits, on account of the brass used in the turbine condenser and in the low-pressure heater on stream in the primary loop.
-
2.
The principal component of the deposits on the fuel element, responsible for ∼90% of the longlived isotope, is the isotope Zn65.
-
3.
Despite the very limited dimensions of the stainless steel surfaces, some Co60 was nevertheless detected in the deposits.
